All moves known by the Pokémon with the Normalize Ability are of the Normal-Type; as a result Normal type Pokémon will benefit from a Same Type Attack Boost. Some moves will work differently as the result of their typing being changed, such as hitting a Ground-Type with Thunder Wave.
Normalize doesn't have an effect in the Overworld.
